Overnight AMD formally announced and lifted the lid on its Radeon RX 6000 series, showcasing a new trio of cards hitting the PC market in November and December - the AMD Radeon RX 6800, Radeon RX 6800 XT, and Radeon RX 6900 XT. And for those wondering how they stack up against NVIDIA’s recent debut of the powerful GeForce RTX 3080, well, AMD was on hand to show exactly that.

Built on AMD RDNA 2 gaming architecture, an extension of the RDNA technology found within the PlayStation 5 and Xbox Series X consoles, each new Radeon card features PCIe 4.0 technology, 16GB of GDDR6 memory, and over 50% higher performance-per-watt compared to the first AMD RDNA-based Radeon 5700 XT. In terms of Big Navi, the Radeon RX 6800 XT which will be priced at $649 USD is set to drop November 18. And in terms of performance it’s a 4K 60fps powerhouse - on par with NVIDIA’s $699 USD RTX GeForce 3080.

Of which AMD presents a comparison across 10 games, highlighting the lower power-draw and titles like Battlefield V, Call of Duty: Modern Warfare, and Forza Horizon 4 where it beats NVIDIA’s own flagship. No doubt thanks in part to the impressive Boost Clock speeds of 2250 MHz.

Something that was also highlighted when switching the resolution to 1440p - where the Radeon RX 6800 XT will reportedly deliver triple-digit performance across the board.

Although ray-tracing was not a focus - in terms of performance - of the presentation, AMD noted that the Radeon 6000 series will fully support DirectX 12 Ultimate - including DirectX Raytracing (DXR), Variable Rate Shading, and Microsoft DirectStorage. In terms of ray-tracing AMD detailed that RDNA 2 adds a “Ray Accelerator engine to each compute unit to deliver real-time lighting, shadow and reflection realism with DXR”. How this stacks up against NVIDIA’s hardware-based RT Cores and DLSS via the AI Tensor Cores remains to be seen. Over the past year DLSS has become something of a must when it comes to visually intensive ray-traced titles. On that front AMD did highlight the PS5 and PC exclusive Godfall as something that will feature ray-tracing and the company's own AMD FidelityFX to boost performance.

RDNA 2 also introduces new AMD tech in the form of CPU-like cache and overclocking (called Rage Mode) - tech born from the strides the company has made with its impressive Ryzen CPU range.
AMD Infinity Cache – A high-performance, last-level data cache suitable for 4K and 1440p gaming with the highest level of detail enabled. 128 MB of on-die cache dramatically reduces latency and power consumption, delivering higher overall gaming performance than traditional architectural designs.

AMD Smart Access Memory – An exclusive feature of systems with AMD Ryzen 5000 Series processors, AMD B550 and X570 motherboards and Radeon RX 6000 Series graphics cards. It gives AMD Ryzen processors greater access to the high-speed GDDR6 graphics memory, accelerating CPU processing and providing up to a 13-percent performance increase on a AMD Radeon RX 6800 XT graphics card in Forza Horizon 4 at 4K when combined with the new Rage Mode one-click overclocking setting.

The more affordable Radeon RX 6800 was also showcased, also out November 18 for $579 USD. Here though the benchmarks were put up against NVIDIA’s own RTX 2080 Ti - the previous gen flagship. That said, like NVIDIA’s RTX 3070, it too will arrive at a much lower price point. Though it's worth noting the AMD lists AMD Smart Access Memory here, something that will be exclusive to systems with AMD Ryzen 5000 Series processors.

“Today’s announcement is the culmination of years of R&D focused on bringing the best of AMD Radeon graphics to the enthusiast and ultra-enthusiast gaming markets, and represents a major evolution in PC gaming,” said Scott Herkelman, corporate vice president and general manager, Graphics Business Unit at AMD. “The new AMD Radeon RX 6800, RX 6800 XT and RX 6900 XT graphics cards deliver world class 4K and 1440p performance in major AAA titles, new levels of immersion with breathtaking life-like visuals, and must-have features that provide the ultimate gaming experiences. I can’t wait for gamers to get these incredible new graphics cards in their hands.”

Finally, and this is where things got very interesting - AMD unveiled the top of the line $999 USD Radeon RX 6900 XT due for release in December. Here, with the overclocked Rage Mode and Ryzen Smart Access boosts enabled it performs on par with the $1499 USD NVIDIA GeForce RTX 3090 using less overall power.

AMD notes that partner cards will also be available from ASUS, Gigabyte, MSI, PowerColor, SAPPHIRE and XFX. With this impressive showing from AMD no doubt the PC graphics space will become more competitive than ever as we move into 2021. Over the next few weeks AMD will be showcasing game-specific examples of the new Radeon RX 6000 series in action - across DIRT 5, Godfall, World of Warcraft: Shadowlands, RiftBreaker, and FarCry 6.

Here's the full presentation from last night.
